Example Embodiment

[0045] The present invention will be further described below with reference to the drawings and specific embodiments.

[0046] Such as figure 1 As shown, a method for optimizing the economics of a monthly equipment maintenance plan based on a network loss reduction index includes the following steps:

[0047] S1. Data generation of benchmark grid operation mode under the economic optimization of monthly maintenance plan for power generation, transmission and transformation equipment:

[0048] Based on the calculation data generated by the monthly planned grid operation mode of the power system, according to the monthly maintenance plan information of the power generation and transmission equipment, the monthly non-changeable maintenance equipment and the equipment with the maximum number of days in the month are based on the maintenance start date and maintenance cycle First arrange for maintenance. Through the conversion settings of the non-changeable maintenance equipment during ...

Abstract

The invention provides a method for economically optimizing a monthly overhaul schedule of equipment based on a transmission loss decline index. The method comprises the following steps: generating reference power grid operation mode data under economic optimization of the monthly overhaul schedule; generating power grid operating mode calculation data of various adjustable overhaul equipment under different overhaul starting dates in an overhaul starting time interval; calculating a monthly transmission loss decline index of various adjustable overhaul equipment; and performing economically optimized arrangement of the adjustable overhaul equipment in a month under a security and stability constraint condition. According to the invention, based on a load flow calculation and time-domain simulation technology of a power system, the total transmission loss of the power grid operation mode under the monthly overhaul schedule of the equipment is reduced through optimal arrangement of the monthly overhaul schedule of the equipment; and thus, decision support is provided for economically optimized arrangement of the monthly overhaul schedule of power generation, transmission and transformation equipment of the power system.

Description

technical field [0001] The invention relates to the technical field of electric power systems and automation thereof, in particular to an economical optimization method for equipment monthly maintenance plans based on a network loss reduction index. Background technique [0002] The optimization of monthly maintenance plan for power generation, transmission and transformation equipment is one of the main contents in the short-term operation plan of the power system. The rationality of the maintenance plan for power generation, transmission and transformation equipment directly affects the economy of power system operation. With the in-depth promotion of lean management of power system operation and the development of computer and communication technologies, the traditional method of arranging equipment maintenance plans based on experience has gradually changed to the direction of intelligent decision-making, in order to achieve energy saving, emission reduction, and loss red...
